CHARLES N. SHAV, OF PETOSKEY, MICHIGANJ MEAT-FREEZER.

SPECIFICATION forming part of Letters Patent No. 316,840, dated April28, 1885. Application mea Npvemter a6, 1834. (No model.)

To all whom, t may concern.-

Beit known that I, CHARLEs N. SHAW, a citizen of the United States ofAmerica, residing at Petoskey, in the county of Emmett and State ofMichigan, have invented certain new and useful Improvements in MeatFreezers, vof which the following is a specicatiomreference being hadtherein to the accompanying drawings.

This invention pertains to improvements in refrigerators, having for itsobject not only to keep meat, oysters, poultry, &c., in a frozencondition and state of preservation, but also to prevent ingress of airin the ice-chamber, and to expedite the storing and removal of thearticles to be preserved 5 and it consists in the combination andarrangement ofthe parts, substantially as hereinafter fully set forthand claimed.

In the accompanying drawings, Figure lis a sectional elevation of therefrigerator. Fig. 2 is a view in perspective embodying my invention.Fig. 3 is a detail view thereof, and Fig. 4 is a view in perspective ofmy invention in its closed condition.

In carrying out my invention I employa refrigerator, A, preferablycylindric, comprising an outer wall, A', and an inner Wall, A, forming achamber, B, for reception of charcoal or other well-known non-conductingmaterial. The two walls A and A2 are connected at the top by anair-tight cover, a'. The4 bottom a of the refrigerator is alsoconstructed with two horizontal Walls, forming a chamber, B, wherein isinserted non conducting packing material.

To the inside of the bottom a of the refrigerator is rigidly secured orcast integral therewith a circular vertical strip, b, which is designedto prevent jarring or displacement of the inner cylindricreceptacle orcan, C.

The receptacle or can C is designed for reception of the article orarticles to be frozen or kept in a state of preservation. The rim of thecan or receptacle() has secured thereto rubber packing b, and inconnection with cover F renders can C air-tight.

The ice-chamber D is formed between the inner wall,A`l, of therefrigerator A and the can or receptacle C.

Removablyhinged or secured to air-tight cover a is a circular lid orcover, E,Which covers the ice-chamber D air-tight, the inner edge of thecover a being provided with rubber packing e on the horizontal face of ashoulder, e', on which the corresponding shoulder of the cover E fits,and is tightly and securely held in position by means of a pivotedthumbpiece, en.

Disposed centrally in the cover E, and of the same width asthe can orreceptacle C, is another circular lid or cover, F, hinged to the coverE, and is rendered air-tight in like manner, rubber packing f beingsecured on the outer edge of the shouldered opening therein. The lid orcover F may be tightly secured by the pivoted thumb-piece f or otherordinary means.

The coldest temperature that can thus be obtained from ice alone isabout thirty-four (34) degrees above zero; but by adding salt to the iceatemperature as low as four (4) degrees above zero may be produced.Consequently, by placing ice in the ice-chamber D and adding sufficientsalt a low temperature may be obtained, and the refrigerator beingair-tight this temperature may be retained. The salt on the ice soonruns off with the drip from the ice through a drip-pipe, G, in thebottom a', leaving the temperature in the icechamber D about the same asbefore the salt was applied to the ice. The temperature in the can orreceptacle C being much colder than that of the ice-chamber D, thetemperature is equalized with that of the receptacle C, thus causing theice to remain solidly frozen and economizing its consumption. Thetemperature in the receptacle C is thus rendered sufficiently cold tokeep fresh meats, sh, oysters, rc., in a frozen condition for severaldays.

From the foregoing it will be seen that access can be had to thereceptacle C through the lid or cover F without exposing the ice inchamber D, which also greatly economizes the ice.

My invention also embodies an elevator, K, which comprises a convenientmeans of storing therein such articles as fresh meats, fish. poultry,and game, and is especially adapted for t-he use of hotels, families,meat-markets, &c.

To the air-tight cover ct, l secure by brack- IOO ets two standards,.G,of corresponding size.

Thesestandards G are connected at'their up' per ends'by a vcross-bar,g,to whichis securedon its upper surface, directly over the center ofcover F, a pulley, H, and on the outer righthand corner is secured apulley, H', the purpose of which will appear Vfurther-on.

To the inner under side of the cover F, I secure three vertical rods, hh and h', the rods h h being directly opposite each other andcconnectedtogether at their upper edges by a bar, Y

h2. To these rods I attach two or more hoops or bands, o, having eachsecured thereto aseries of hooks, o', for hanging thereon `to beIpreserved fresh meat, Ste. The hoops or bands extend only a shortdistance beyond the two opposite rods h-h, to allow of more convenientlaccess to the yinterior of the elevator 'K and Vstoring Vor obtainingof articles to be preserved. Thebar or rod 'L has a tenon formed oueachend,whicl1 is adapted to a corresponding mortise, mprovided in thestandards'G, vwhich serves as a guide for the cupboard K.

To the key in the opening in the eyebolt Z is secured an elevating-rope,M, which is'passcd u-p through an opening in the bar g and over pulleyH, thence down vover pulley 'I-I, and -to Vthe end of `this rope isconnected a counterbalancing-Weight, N, for elevating the cupboard K.

NVhendesired, I dispense with the hoops or bands 0 andtheir hooks, andin lieu thereof 1I attach four or more shelves, I, forming a cupboard,K, as clearly seen in Fig. 3.

'It will be seen that my invention is both `durable andeconomical, andthat it prevents any waste of ice from exposure, that the lid or cover Fwhen opened or removed doesV :not expose the ice, as there is noconnection betweenthe receptacle() and chamber D,'and thusconstructedthe article or articles in the receptacle C are not'aiffected by themoisture Vof the.iceehamber.

Iam aware that it is not broadly new .to

construct in-connection with a refrigerator an velevator for-receptionzand storing of articles Vto be preserved; but my invention isdesigned as an improvement on such devices, and is intended mainly toprovide in one and the same device means for retaining the ice in afrozen condition Vfora greater period of time than heretofore, and torender the invention particularly adapted for the storage of freshmeats, which alone is an advantage over similar inventions as heretoforeconstructed, they having been found not applicable for such purpose.

Anotherimportant feature of my invention is the manner in which Iconstruct that part of theV elevator which is inclosed -within'the wallsof the refrigerator to permit Vthe ready access V,to the articles storedthereimand to convert the same into a cupboard, thereby vrendering 4theinventionY specially applicable 'for the use of families.

Having thusfully described my invention,

Vwhat I claim, and desire to secure by Letters Patent, is-

l. The elevator K, having bars orrods Vh h and h, hoops or bands o, and.hooks ,-o, arranged'for the purpose'hereiu shown and described.

2. A refrigerator having the removable lid F, elevator K, and lioopsor`bands 0,7.in combination with the cover E andairftightcover
